Glazier&#39;s nail



1932- F. H. WASHKO v 1,887,253

GLAZIERS NAIL Filed July 28, 1930 INVENTOR.

\ ATTORNEY.

Patented Nov. .8, 1932 PATENT OFFICE FRANK H. WASHKO, BEDIEORLD, OHIO GLAZIERS' NAIL Application filed July 28, 1930. Serial No. 471,396.

The objects of this invention are to provide fastening nails for the glass panes of a greenhouse roof, which are so constructed that the downward pressure of the overlapping panel of glass can not bend or deflect them from their positions in the'sash bars to which they are attached.

To obtain these and other useful results the nails are provided with laterally offset points or bearings upon which the pressure on the nail from above is received, and prevent the distortion or displacement of the nail and the consequent slipping of the glass and leaking of the roof, and also reducing the amount expended for upkeep and repairs of the roof.

The invention is hereinafter more fully described illustrated in the accompanying drawing and specifically pointed out in the claim.

In the accompanying drawing, Fig. 1 is a transverse section of a vertical roof bar, showing the manner of employing the nails to secure the glass thereon. Fig. 2 is a vertical transverse section of the overlapping are formed additional'bearing or fulcrum points or surfaces which are shown as parallel projecting points F, F, that enter the wood at points spaced from the main points and hence prevent the nail from slipping or from being bent over by the weight of the glass pressing down upon them.

Smaller nails G, G, may also be employed to bear down upon and hold the overlapping pane of glass from rising above the other nails.

It is preferable to have the two longitudinal edges of the nail parallel with each other, since in that manner the greatest amount of resistance to tilting is obtained.

In use, the flat glaziers point having parallel upper and lower faces and parallel longitudinal edges is laid upon the lower 7. pane with the longer edge engaged with the lower edge of the upper pane.

The inclined outer end of the nail presents a projectionclosely adjacent to the end of the upper pane, and in continuation of the longer side of the nail, which is then struck with a hammer or dull chisel and the nail will be driven perfectly straight into the sash.

The spur F or short point acts as a brace to prevent the nail from being forced out of line.

The long and short points may be easily obtained by cutting or stamping an angular longitudinal recess in the end of the plate with its major axis offset from or inclined to the major axis of the plate as shown in Fig. 5. I

The device fills a long felt want in the provision of a flat glaziers point that can not be driven out of line and willsupport V the lower edge of the upper pane.

I claim:

A glaziers nail for securing the overlapping edges of glass panes in a green house roof to, the roof bars, comprising, a sheet metal body having a longitudinal edge applied to the transverse edge of said pane, said edge terminating in a point having the out- .er edge inclined outwardly, said body having a narrow fiat upper transverse face adjacent to said longitudinal edge positioned to receive the blow of a hammer, said body bein provided with an outwardly and downward ly inclined point, shorter than said longitudinal edge and positioned to prevent the tilting of said nail outwardly when driven, said inclined point having outwardy inclined up per and lower edges and a short outer vertical edge connecting the same.

In testimony whereof I aflix my signature.

- FRANK H. WASHKO.
